Bloch MB.200
The MB.200 was a French bomber aircraft of the 1930s designed and built by Societé des Avions Marcel Bloch. A twin-engined high-winged monoplane with a fixed undercarriage, over 200 MB.200s were built for the French Air Force, and the type was also licence built by Czechoslovakia, but it soon became obsolete, and was largely phased out by the start of the Second World War. Development and design The Bloch MB.200 was designed in response to a 1932 requirement for a new day/night bomber to equip the French Air Force. It was a high-winged all-metal cantilever monoplane, with a slab-sided fuselage, powered by two Gnome & Rhône 14Kirs radial engines. It had a fixed tailwheel undercarriage and featured an enclosed cockpit for the pilots. Defensive machine guns were in nose and dorsal gun turrets and an under fuselage gondola.Taylor 1981, p.23. The first of three prototypes flew on 26 June 1933. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000".

Radial Engine
The radial engine is a reciprocating type internal combustion engine configuration in which the cylinders "radiate" outward from a central crankcase like the spokes of a wheel. It resembles a stylized star when viewed from the front, and is called a "star engine" in some other languages. The radial configuration was commonly used for aircraft engines before gas turbine engines became predominant. Engine operation Since the axes of the cylinders are coplanar, the connecting rods cannot all be directly attached to the crankshaft unless mechanically complex forked connecting rods are used, none of which have been successful. Instead, the pistons are connected to the crankshaft with a master-and-articulating-rod assembly. One piston, the uppermost one in the animation, has a master rod with a direct attachment to the crankshaft. The remaining pistons pin their connecting rods' attachments to rings around the edge of the master rod. Extra "rows" of radial cylinders can be added i ...

Stressed Skin
In mechanical engineering, stressed skin is a type of rigid construction, intermediate between monocoque and a rigid frame with a non-loaded covering. A stressed skin structure has its compression-taking elements localized and its tension-taking elements distributed. Typically, the main frame has rectangular structure and is triangulated by the covering. Description A framework box can be distorted from being square, so it isn't rigid by itself, however adding diagonals that take either tension or compression fixes this, because the box cannot deviate from right angles without altering the diagonals. Sometimes flexible members like wires are used to provide tension, or rigid compression frames are used, as with a Warren or Pratt truss, however both these are full frame structures. When the skin or outer covering is in tension so that it provides a significant portion of the rigidity, the structure is said to have a stressed skin design. This may also be referred to as semi-mon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Airframe
The mechanical structure of an aircraft is known as the airframe. This structure is typically considered to include the fuselage, undercarriage, empennage and wings, and excludes the propulsion system. Airframe design is a field of aerospace engineering that combines aerodynamics, materials technology and manufacturing methods with a focus on weight, strength and aerodynamic drag, as well as reliability and cost.Michael C. Y. Niu (1988). ''Airframe Structural Design''. Conmilit Press LTD. History Modern airframe history began in the United States when a 1903 wood biplane made by Orville and Wilbur Wright showed the potential of fixed-wing designs. In 1912 the Deperdussin Monocoque pioneered the light, strong and streamlined monocoque fuselage formed of thin plywood layers over a circular frame, achieving . First World War Many early developments were spurred by military needs during World War I. Well known aircraft from that era include the Dutch designer Anth ...

Aluminium
Aluminium (aluminum in American and Canadian English) is a chemical element with the symbol Al and atomic number 13. Aluminium has a density lower than those of other common metals, at approximately one third that of steel. It has a great affinity towards oxygen, and forms a protective layer of oxide on the surface when exposed to air. Aluminium visually resembles silver, both in its color and in its great ability to reflect light. It is soft, non-magnetic and ductile. It has one stable isotope, 27Al; this isotope is very common, making aluminium the twelfth most common element in the Universe. The radioactivity of 26Al is used in radiodating. Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al3+ is small and highly charged; as such, it is polarizing, and bonds aluminium forms tend towards covalency. The strong affinity tow ...

Ateliers Et Chantiers De La Loire
Ateliers et Chantiers de la Loire (ACL) was a French shipbuilding company of the late 19th and early 20th century. The name translates roughly to English as "Workshops and Shipyard of the Loire". Early years In the eighteenth century Nantes had been the biggest French port, and the Loire had a major shipbuilding industry. A prime example was Dubigeon established in 1760. In the nineteenth century Nantes was surpassed by Le Havre and Marseille. In the first half of the nineteenth century a port was developed at Saint-Nazaire for ships that could no longer reach Nantes. In the second half of the nineteenth century industrialization got under way in Nantes and Saint-Nazaire. In 1861 a Scottish engineer founded the Chantiers de Penhoët at Saint-Nazaire. Ateliers et Chantiers de la Loire (ACL) was formed in 1881 in Nantes by Jollet Babin to take advantage of the expansion of the French Navy. The shipyard was built at Prairie du Lac, near the Dubigeon yard, and the following yea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Farman F
Farman Aviation Works (french: Avions Farman) was a French aircraft company founded and run by the brothers Richard, Henri, and Maurice Farman. They designed and constructed aircraft and engines from 1908 until 1936; during the French nationalization and rationalization of its aeronautical industry, Farman's assets were assigned to the ''Société Nationale de Constructions Aéronautiques du Centre'' (SNCAC). In 1941 the Farman brothers reestablished the firm as the "''Société Anonyme des Usines Farman''" (SAUF), but only three years later it was absorbed by Sud-Ouest. Maurice's son, Marcel Farman, reestablished the SAUF in 1952, but his effort proved unsuccessful and the firm was dissolved in 1956. The Farman brothers designed and built more than 200 types of aircraft between 1908 and 1941. They also built cars until 1931 and boats until 1930. Background In 1907, Henri Farman bought his first aircraft from Gabriel Voisin and soon began to improve the design of the air ...
